STRONGYLIUM. 369 
b. Elytra moderately long, with an oblique reddish-testaceous stripe extending from 
the shoulders nearly to the apex. 
49. Strongylium discoidale. 
Strongylium discoidale, Mak]. Monogr. p. 231; Act. Soc. Fenn. viii. part 1, p. 339°. 
Hab. Mexico, Cordova (Sailé 1). 
This species is allied to S. marginale; but the thorax is shorter and very coarsely 
punctured; the scutellum is red; and the elytra are much shorter, somewhat similarly 
striped, and, like the rest of the surface, greenish-zneous in tint. 
50. Strongylium curticorne. (Tab. XVI. fig. 6, 3.) 
Moderately elongate, subcylindrical, not very convex, bluish-violet, rather dull. Head very coarsely and closely 
punctured, the epistoma more finely and sparingly so, shallowly longitudinally impressed between the eyes, 
the latter rather small and widely separated; antenne ( ) short, stout, joint 4 triangular, rather shorter 
but very much wider than 3, joints 5-10 wider than 4, equal in width and subtransverse, 11 rather longer 
than 10 and short ovate; prothorax a little broader than long, rather convex, the sides very obsoletely 
margined about the middle (the indistinct margin not visible from above), slightly rounded, and narrowing 
a little in front, the base and apex straight, the anterior angles obtuse, the hind angles subrectangular, 
the basal foves shallow, the disc impressed in the middle behind, the surface very coarsely and closely 
punctured ; scutellum greenish, slightly impressed; elytra narrow, moderately long, a little depressed on 
the disc, somewhat coarsely striate-punctate (the punctures approximate, and transverse in shape), the 
interstices a little convex towards the sides and strongly so at the apex, almost smooth, the surface 
reddish-testaceous, with a broad bluish-black sutural stripe extending from a little below the scutellum to 
the apex and there confluent with a similarly-coloured marginal stripe extending upwards to within a 
short distance of the base; beneath more shining, slightly pubescent, the sides of the meso- and of the 
metasternum and the side pieces, and the flanks of the prothorax exceedingly coarsely, the ventral surface 
finely, punctured; legs short (the tibiee especially) and comparatively stout, coarsely punctured, the first 
joint of the posterior tarsi as long as the apical one; the tibiz a little curved and the anterior and 
posterior pairs pubescent within in the male. 
Length 8 millim.; breadth 23 millim. (¢.) 
Hab. Mexico, Tapachula in Chiapas (£7ége). 
A single example found by Herr Hoge on the lower part of the South Mexican 
Pacific slope. S. curticorne can be at once separated from the numerous allied forms 
by its comparatively short legs and antenne; in the system of coloration of its 
elytra it resembles S. marginale. 
c. Elytra shorter, coarsely punctured, with the base, the lateral margins in front, and a 
short basal streak on each, red; eyes small. 
51. Strongylium ramosum. (Tab. XVI. fig. 7, 3.) 
Strongylium ramosum, Miakl. Monogr. p. 232; Act. Soc. Fenn. viii. part 1, p. 340°.
